subvolume nomenclature
I seem to have the following subvolumes of my filesystem: # btrfs sub li / ID 256 top level 5 path @ ID 257 top level 5 path @home ID 258 top level 5 path @/etc/apt/oneiric I *think* the last one is there due to a: # btrfsctl -s oneiric / that I did prior to doing an upgrade. I can't seem to figure out the nomenclature to delete it though: # btrfs sub de /@/etc/apt/oneiric ERROR: error accessing '/@/etc/apt/oneiric' I've tried lots of other combinations with no luck. Can anyone give me a hint (or the answer :-) )? Cheers, b. signature.asc Description: OpenPGP digital signature
